Brussels is same source as #D364.su, but better quality (although still below average)
Dresden is the same source as Dresden film quality is also poor, though performance is strong
Bonus TV footage is nice
Half-D1 (half-resolution) standalone NTSC transfer

Dresden is the same footage as that on D687. However, the D687 Dresden is PAL format, better quality, and divided into proper chapters. D374 was recorded on a standalone DVD recorder and converted to NTSC. This suggests that the source was either D687, or that a PAL tape was converted to NTSC and then used as the source on a DVD recorder.
